摘要:
The device (10) for the intermixing of two components, such as synthetic compound and hardener, for the production of a dual or multi-component compound, such as filler for repair work on sheet metal is comprised of an evacuable mixing container (50) which can be opened at the top, in the mixing chamber (20) of which a rotatingly driven mixing disk (30) that is removable from the mixing container (50) and a vane-like (41) mixing member (40) are disposed, which, as compared to the rotating mixing disk (30), is vertically and stationarily arranged in the mixing chamber and, with the aid of a driving means (149), is alternately swivelable about its vertical shaft (49) by small angular values, while the cover portion (54) of the mixing container (50), while in the operative position, is retained by means of a vacuum on the circumferential rim of the container side wall (52) (FIG. 1).

A mixer is comprised of a flat rotating disc over which is placed a confining wall that begins near the center of the disc and curves outwardly, generally spirallike, terminating at the outer edge of the disc. Material is supplied at the center of the rotating disc and is guided by the confining wall outwardly to the outer edge of the disc. Mixing paddles are disposed in the path of the material. An adjustable gate is provided at the exit opening defined by the terminal edge of the confining wall and is adjustably mounted for closing off or restricting the flow of material through the exit opening.

A concrete mixing vehicle having a retractable tag axle assembly and a distribution chute is disclosed. To ensure that the tag axle assembly does not come into contact with the distribution chute as the tag axle assembly as it moves between a first ground engaging position and a second elevated position, a limit switch is provided in the control circuit for the tag axle assembly. The limit switch only permits movement of the tag axle assembly when the distribution chute is outside of the tag axle assembly's path of travel as it moves between said first and second positions.
摘要:
A method for producing colloidal mixtures, especially water-cement mixtures with or without further solid additions, comprising the steps of feeding the material for forming the colloidal mixture into a container, stirring the material fed into the container by a blade stirrer driven by a motor at a circumferential speed at the outer diameter of the blade stirrer of at least 500 and preferably 1,500 meters per minute, continuously measuring the variations in the energy take-up of the motor, and stopping stirring of the material when the continuously observed energy take-up indicates a sudden transition from a fluctuating to a substantially steady course; and an apparatus for carrying out this method.
摘要:
This mixer comprises a cylindrical tank 5 having a fixed lateral wall 7 and a rotary bottom 9 rotatably mounted inside the lower part of the fixed lateral wall. It is characterized in that the rotary bottom 9 comprises a peripheral collar 18 overhanging its lateral face and forming an annular gap with wall 7, in that an annular projection 21 carried by this latter extends under the collar and defines therewith an annular chamber 22 extending between the lateral face of bottom 9 and wall 7, and in that the chamber communicates with the tank through the annular gap and emerges under the bottom 9 into a narrow annular slit provided between the lateral face of the bottom and the projection 21.

A hydraulic concrete mixer includes a drum (110) having a mixing blade (120) attached to an interior thereof, a frame (130) supporting the drum, an engine (140) mounted on the frame, and a drive train (150) extending through at least a portion of the drum. The drive train includes: a hydraulic motor (210); a first rigid plate (220) between the hydraulic motor and the drum; a second rigid plate (230) inside the drum and coupled to the first rigid plate such that a portion of the drum is held between and in fixed relationship to the first rigid plate and the second rigid plate; a first shaft (240) inside the drum and adjacent to the second rigid plate; a second shaft (250) adjacent to the first shaft; and a mounting plate (260) coupled to the second shaft.
摘要:
A truck mounted concrete mixer has a hydraulic drive through a gear reduction unit at the forward end of the mixing drum. A support column attached to the truck frame supports the gear reduction unit in a manner to minimize transmittal of truck frame deflections under operating condition to the gears in the gear reduction unit. Specifically, the front of the gear reduction unit is connected to the support column at a point in front of the drum support shaft while the rear of the gear reduction unit is rigidly connected to the support column on a line transverse to the axis of the drum and below the point of support of the forward end of the drum.
